MAX706SCUA+

The MAX706SCUA+ is a +3V voltage monitoring low cost microprocessor (μP) supervisory circuit in 8 pin µMAX package. This supervisory circuit reduces the complexity and number of components required to monitor +3V power supply levels in +3V to +5V μP systems. It significantly improves system reliability and accuracy compared to separate ICs or discrete components. This device provides reset output during power-up, power-down and brown-out conditions. An independent watchdog output will goes low if watchdog input has not been toggled within 1.6s. The MAX706S provides 1.25V threshold detector for power fail warning, low battery detection or for monitoring power supply other than main supply. It also provides active-low manual reset input. This device is used in computers, controllers, intelligent instruments, critical μP power monitoring and battery powered equipments.
